Can a Water-Damaged Car Still Be Used?

If a vehicle has been waterlogged, it is recommended not to drive or use it anymore. Below is extended information about the hazards of water-damaged cars: 1. The electronic control system inside the car: The mixed rainwater is highly corrosive and can affect the functionality of electrical components, especially impacting future use. Since most cars are equipped with electronic control systems (such as the engine ECU, ABS system, SRS system, GPS navigation, etc.), if water enters, it can cause short circuits in the ECU's internal IC circuit board and rust spots on connector terminals. This gradually leads to corrosion of metal parts, resulting in poor contact in circuits and even short circuits that may cause burning. 2. The engine: The engine connecting rod may deform, causing the piston stroke to shorten, which prevents gases from being fully compressed. The piston rings may lose elasticity or fail to seal properly, leading to gas leakage. Compressed gas may escape into the crankcase. If the intake and exhaust valves do not seal properly when closed, compressed gas may leak into the intake and exhaust manifolds.
Regarding whether a water-damaged car can still be used, based on my years of experience in auto repair, the risks are too high to ignore. If water reaches the engine or seat level, the car is essentially totaled because water can seep inside, causing short circuits and corroding components. I've seen many cases where owners experienced electrical fires or accidents within six months after repairs. Especially for cars submerged in saltwater, the corrosion is more severe, leaving behind mold and foul odors. Safety comes first—starting such a car may lead to loss of control, and stalling on the highway can have serious consequences. I recommend scrapping it rather than taking the risk. If the flooding is severe, tow it directly to a scrapyard—life is more valuable than a car. Always avoid parking in low-lying areas and check drainage channels after rain. Remember, flood-damaged cars pose significant hidden dangers and are unsuitable for daily driving.
